Whenever an app is executed on a server, it is loaded into the physical memory. In the event that you run a resource-demanding script, or if you simply add more scripts on your websites and you get loads of visitors, you could encounter a case where your Virtual Private Server has too little memory to run all the programs and freezes for that reason, which means your sites will stop working correctly and that the website visitors shall start seeing error messages. To avoid this type of a scenario, you'll be able to take advantage of the RAM upgrade that we are offering and increase the amount of physical memory at your disposal without changing your entire plan. In this way, you may pay only for the resources you actually need and not for additional disk space or higher Processor speeds that you won't really use, for instance. With the upgrade, you'll be able to guarantee the faultless functioning of your sites, which also means a better experience for your website visitors.
